I think your reasoning is pretty sound. One of my best little ponds has some smallies in it, and they are probably both sexes. My thought has been, that if the smallies reproduce I'm going to run the seine and collect the little SMB. They would be extremely easy and profitable to sell. In your case, if you had bunches of little SMB you could contact a local fish guy and trade. SMB are usually the easiest fish to barter or trade with.
